Properties Nontoxic grey powder. Relative density:
1.32. Melting point =135°C. It is soluble in acetone, slightly soluble
in dichloroethane, benzene, hot water and hot alkaline solutions,
insoluble in gasoline and water. Stable for storage.
Applications Because it has excellent protective
character to ozone and oxygen, TPPD can be used as Antioxidant for CR,
NR, BR, SBR and their latexes. TPPD can inhibit copper oxidation and
manganese oxidation, and especially can inhibit the damage to fiber
materials by chlorine released during CR's aging. TPPD is dispersible,
so it can be directly added into rubber, or be added into latex in the
form of aqueous dispersoid. When TPPD is used in CR with Antioxidant ODA
as co-reagent, it will perform its best thermal resistance, reduce the
plasticity of unvulcanized CR, and decrease the degree of shrinkage
during calendering, so is helpful to adjust the size of semi finished
articles.TPPD is mainly used to produce rubberized fabric, electric
insulative products and light color industrial products. Normal dosage
in CR is 1-2 phr.
Packing Coextruded paper bags lined with polyethylene film bags. Net weight 25 kg per bags.
